Hi Everyone,I've always stayed away from using silicone on my RV's for the many reasons stated on this forum, BUT when I was at my local RV shop yesterday the tech was admiring my rig when he noticed some missing caulk on a vertical seam ( I am in the process of removing some old caulk an re-applying). He asked what I was going to use, I told him I had used Geocel ProFlexRV sealant and did not like it at all and was removing it where I had applied it. He told me to use 100% silicone to caulk the outside vertical seams. It is what they use at the shop all the time on all the RV's. He just said make sure it is 100% silicone and not a blend of any kind.What do you think?

That would be the last time I let that shop work on my rv.

What do you suggest for sealing the vertical seams? I tend to agree that silicone is not the answer.

Ask him if he will re-do any silicone caulking that he applied when time comes to recaulkSilicone will NOT stick to silicone so it has to be COMPLETELY removed.....that includes the residue which is time/labor involved BEFORE you can recaulk using ANYTHING else.Like above post.....glad to know he uses it so I could STOP him before and then not go backI like ProFlex. Small cup of water and a WET finger helps.Dicor Non-Sagging works well alsoAnd they need to be FRESH (shelf life) and unopened (use it/can't save it).

Well,I have used silicone for years and never had an issue with it.The internet hates silicone but there are alot of RV places that use it like you just posted..My reply was from using silicone off and on for like 50 years..Your mileage may differ.

Silicone only belongs in breast implants. not on an RV. I use Sikaflex myself.
